Concentration of metals in soft organs of Lamellidens marginalis from Krishna river at Ankali, Maharashtra (India)
Description
ABSTRACT
The present study deals with the heavy metal concentration in soft tissue of freshwater lamellibranch mollusks inhabiting in the Krishna river at Ankali. The bivalve, L. marginalis (Lamarck) was selected in the present study. This species of mollusks was subjected for detection of heavy metals such as Nickel, Zinc, Lead and Aluminium from various soft tissues such as mantle, gill, siphon, foot, hepatopancreas and gonads. The work was carried out seasonally for the period from January 2013 to December 2013 and values were recorded in ppm. Accumulation of Zn was maximum in gills, while minimum in foot in different seasons. Similarly accumulation of Ni, Pb and Al was maximum in gonads whereas, it was minimum in siphon in different seasons
Keywords: Heavy metals, Soft organs, L. Marginalis, Krishna River
